Following along with what you said (above), once the thermostat DOES open up --- no matter WHAT its temperature rating might be --- won't the coolant STILL "...circulate too fast to allow for optimum heat transfer" through the rad, as you describe...? And then at that point won't the temperature simply continue to rise, higher & higher...?
The DIS-ADVANTAGE to HAVING a thermostat under those conditions is that the coolant temperature will have been given an opportunity to reach 160F, 180F, 195F --- whatever --- BEFORE being allowed to at last move through the system...where it would do little good, by your explanation...
I'm NOT trying to be a smart-alec here, or anything like that, at all --- I'm just trying to get a logical handle on this so that even I might understand it (you see, my '78 T/A runs a tad too hot for my liking, too).

If you are NOT a fan of thermostats,what you need to do is take the center section out of one & just install the outer flat ring/plate as a restrictor.
This will slow the coolant down enough to let the radiator do it's job properly.
Just for fun,you might want to install a 160 or 180 T-stat in your 78 & see if it actually DOES run cooler than with NO thermostat.
FYI: if your 78 came WITHOUT A/C from the factory,it likely came with a 2 row radiator.If you haven't upgraded to a 3 row,that would ALSO be a good idea.
(2 row offers only "marginal" cooling at best)
